PLATERO ETAL REINF'ORCED TILE ARCH Filed March 8, 1948 Patented Mar. 11, y 1952 Armando Bocage llatero,` `Luis Garcia Pardo,` and Julio Jorge Bonsignore, Montevideo, Uruguay Applicati'oiiMarch 8, 1948, SeiallN'o. 13,613 In Uruguay March 28, 1947 This invention refers to prefabricated rooing elements which can be installed without the use of frames, scaffolding and/or other similar devices known in the art, thus making possible the roofing of any building with a minimum amount of preparatory work, and with saving in the cost of labor and materials, such as timber, nails, screws, wires, props, etc., which are of no value when the frames, scaffolding etc., used heretofore are dismantled.

Another feature of the invention is that the prefabrcated elements are joined together in situ by means of reinforcing ribs an'd forni a light and strong roof.

In order that the invention may be clearly understood reference is had to the accompanying drawings in which Fig. 1 is a vertical view in perspective of part of two L roofing elements showing the respective strengthening bars.

Fig. 2 is a vertical cross section View of the L elements (Fig. 1).

Fig. 3 is a vertical longitudinal view of the L elements (Fig. 1).

Fig. 4 is a vertical view in perspective of the box shaped element which is mounted on the L elements.

Fig. 5 is a vertical view in perspective of the box shaped element (Fig. 4) raised on one of its sides.

Fig. 6 is a vertical cross section view through the element of Fig. 4.

Fig. 7 is a plan view in detail of the manner in which the roong elements are assembled in situ.

Fig. 8 is a vertical view in perspective showing a modified construction of the box shaped roofing element, having two vertical sides open.

Fig. 9 is a vertical cross section view through the element of Fig. 8.

Figs. 10 and 11 are vertical views in perspective of a modied construction of the box shaped roofing element having a iluted surface for carrying hollow roong tiles.

Fig. 12 is a vertical View in perspective showing in detail the manner in which the roong tiles are placed on the box shaped rooting element, and these latter placed on the L elements.

In these figures A are L-shaped elements having a vertical arm I and a horizontal arm 2 with reinforcing bars 3, these elements being of substantial length to permit their ends to rest on the opposite walls 4 (Fig. 7) of the room and/or other construction to be roofed. The L pieces are made of reinforced concrete, and are set in 2 Claims. (01.72563) place in pairs with their vertical arms l against each other. The longitudinal free border 5 of the horizontal arms 2 are beveled so that when connected to the longitudinal free border 5 of the next horizontal arms 2, these beveled portions will form a channel E to carry a bar 7 (Fig. 7) for 'further strengthening the roof. The vertical arms I of the L elements have a plurality of holes 8., preferably 'of egg-shaped section from -which run transversal grooves I' to lighten the weight of the L 'elements and also to permit the passage of and to receive the cross-bars 9 also for further strengthening the roof.

B are `shaped 'box-elements preferably square and covered at the top, said boxes having on two opposite walls perpendicular cuts II so as to permit each one of the boxes to be mounted on the vertical arms I of each pair of L pieces as shown in Fig. 7. The four 'sides or walls I2 of these boxes B are stepped as at I3 and slant inwardly and upwardly, so that when placed on the L elements at the proper distance one from the other they will form a Wedgelike space which is afterwards lled with concrete to form the ribs I4 as shown in Fig. 7.

From the foregoing it will be understood that for the construction of roofs according to the invention, the prefabricated pieces L, with their ends resting on opposite walls, are placed in pairs with their vertical arms contacting, and the borders of their horizontal arms contacting with the borders of the next pair, the necessary number of pairs being placed until the space to be roofed is closed. The L pieces being thus in position the box shaped pieces B are mounted on the vertical arms of the L pieces (Fig. 7) and afterwards the strengthening bars 'I are placed in the channel 6 formed by the beveled longitudinal edges of the horizontal arms 2 of the L pieces, the cross bars 9 being placed on the cross wise grooves I0 and through the holes 8, as illustrated in Fig. 7.

Once the parts are in place, concrete is poured in the spaces between the boxes B to form the ribs I4 and the complete roof as shown in Fig. 7. The stepped parts I3 of walls 4 and the grooves I0 also constitute means to prevent any possible displacement of ribs I4.

In the modication shown in Figs. 8 and 9, the box shaped element B is replaced by parallelepiped element C having both ends open. These elements C are placed on the L pieces as already described in connection with box shaped pieces B.

In the modication shown in Figs. 10, 11, and 12, the parallelepiped elements D have a groove I 5 in the internal surface of the top of the element which engages the borders I6 of the pair of the vertical arms of the L pieces as shown in Fig. 12. The upper part or top l1 of the parallelepiped pieces D have fiuted surfaces so as to conveniently carry the roofing tiles when these are used. The angles formed by the top and sides of the element are partly uted so that when two of these pieces are placed lengthwise side by side, the concrete poured between the said elements will complete the uting which will be of the same width as the others to properly carry the tiles. The strengthening bars 1 and 9 are placed and the concrete then poured in manner already mentioned in connection with Fig. 7.

In cases where a double row of tiles (hollow roofing tile) are used, the rst or lower row of tiles may be placed on the roong elements when these latter are made in the factory and the tiles which correspond to the concrete rib are placed in situ when the cement forming the rib is poured.

We claim:

1. In a reinforced prefabricated concrete roofing, roong elements comprising L-shaped members placed in pairs with their vertical arms contacting each other, said vertical arms having a plurality of egg-shaped holes therethrough, beveled longitudinal borders on the horizontal arms of said L-shaped members, said members being placed adjacent one another and said beveled borders of one said member contacting the corresponding beveled borders of the next member to form longitudinal channels, strengthening bars placed in said longitudinal channels, the upper surface of the horizontal arms of said members having crosswise grooves connecting into and extending from said egg-shaped holes to the border of the horizontal arms.

2. In a reinforced prefrabricated concrete roofing as claimed in claim 1, and wherein box shaped elements having cuts on two opposite lateral walls thereof are mounted on the vertical arms of the L-shaped members, said cuts fitting around and over the vertical arms of the L-shaped members, the outside surface of the walls of said boxes being stepped and slanting inwardly and upwardly to form wedge-like spaces between adjacent boxes, strengthening bars inserted in said wedge-like spaces resting in said longitudinal channels and in said crosswise grooves and passing through said egg-shaped holes, said wedgelike spaces being filled with concrete which also passes through the egg-shaped holes, open in the Wedge-like spaces, in the L-shaped members to form continuous concrete ribs which unite all the members and form a solid roof construction.
